To all whom it may concern:

Be it known that we, ANTHONY P. GI-

UNTA and CHARLES P. GIUNTA, citizens of the United States, residing at Philadelphia,

county of Philadelphia, and State of Pennsylvania, have invented certain new and use ful Improvements in Crushers, of which the following is a specification.

Our invention relates to orushers adapted for use in crushing fruitsand vegetables.

The objects are to'provide a crusher of simple and strong construction which will crush material more efiicientlythan heretofore possible, which will be flexible to allow hard materials to pass therethrough, and which may be quickly assembled- These objects, and other advantageous ends which will be described hereinafter, we attain in the following manner, reference beinghad to the accompanying drawings in which Figure 1 is a vertical central section through a crusher constructed in accordance with our invention.

Figure 2 an enlarged fragmentary side view of the crusher shown in Figure 1, and

a section on line 3 3 of Fig- Figure ure 2. v v v v Referring to the drawings, 1 indicates a frame which consists of a pair ofsupports 2 and a pair of spacers 3 disposed between the supports. The spacers are secured to the supports by nails 1 or otherwise to hold them against lateral displacement. A bearing bracket 5 is mounted at the outer side of each support 2 and secured thereto by tie rods 6 passing through brackets 5 and tie rods serve a dual function, first, to secure each of the brackets 5 to the supports 2, and second, to hold the supports in contact with the spacers. 7

Each bracket 5 is provided with a fixed bearing 7, a guideway 8 and a wall 9 in the end of the guideway. A bearing block 10, slidable in guideway 8, is provided with a plunger 11 sliding in wallt). A coiled spring 12 is mounted on the plunger between wall 9 and block 10. The crushing means are mounted in blocks and bearings 7. Hard material, which cannot be crushed, will readilypass between thecrushing elements because the spring pressed blocks 10 permit the crushing elements to yield.

The crushing means includes a pair of shafts 13 and 1% mounted. in bearings 1 gears 15 mounted on the shafts and a pair of crushing rolls 16 keyed to the shafts within the frame. The crushing rolls are provided with a plurality of annular and blocks 10, a pair of meshing rows of teeth 17 arranged so that the teeth of one row will be opposite the grooves between the teeth of the adjacent row. This arrangement provides compartments 18 between the teeth'wherein thematerial to be crushed will be confined during the crushing action. The ends 19 of the teeth of the end rows are provided with an integral plate 20 to form compartments 21 between the teeth similar to the compartments 18. The meshing teeth adj acent plate 20 are cut away at 22 asufiicient distance to allow proper meshing. A hopper 23 of suitable construction rests on supports 2 and spacers 8, and is locked thereto by clips 24 secured to the spacers and lugs 25' secured to the hopper and engaging within the clips.

To crush material with our improved crusher, the material is fed into the hopper and shaft 13 rotated. Gears 15 will cause shafts 13 and 14' and crushing rolls 16 to rotate in opposite directions. Asthe rolls rotate the material falling within the compartments 18 and 21 will be confined therein during the crushing action of the meshing teeth so that none of the material will be forced out throughthe ends of the compartments as is usual with rolls having plain non-staggered teeth. If hard material happens to fall between the rolls the spring pressed bearing blocks 10 will move against the action of the spring and allow the noncrushable hard material to pass between the rolls. During the movement of blocks 10 against the action ofspring 12, plungers 11 hold blocks 10 against turning with shaft 14- and thereby preventthe corners of the blocks 1 from digging into the. guideway during the sliding of the block, thus lengthening the lot bearing bracket 5 and support 2 on the other I side by tie rodst, a strongand durable frame. and support is provided and one which may be quickly assembled.

While we have described our invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence we do not limit ourselves to the precise construction set forth, but consider that we are at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. A crusher including a pair of parallel supports held apart by wall members, fixed and slidable bearings in the supports, a pair of cooperating crushing rolls mounted between said wall members and each having its axis extending through said parallel supports, the axis of one roll being mounted in the fixed bearings and that of the other roll being mounted in the slidable bearings,

and tie-rods extending through the bearings and parallel supports exteriorly of the wall members, substantially as described.

2. A crusher including side and end walls, fixed and slidable bearings in the end walls, a pair of rollers located within the space between said walls and mounted respectively in the slidable bearings and in the fixed bearings, said rolls having a plurality of annular rows of cooperating teeth and tooth receiving compartments, each tooth receiving compartment having side walls and end walls for confining therewithin the material to be crushed during the crushing action, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
